Influence of a Coronal Mass Ejection on the Solar Cosmic Ray Acceleration by a Shock Wave in the Lower Solar Corona

Based on the theory of diffusive shock acceleration of charged particles, we have theoretically studied the spectra of protons produced by a shock wave driven by a coronal mass ejection with a velocity of 1000 km s –1 in the lower solar corona with known solar plasma parameters using numerical methods. We show that protons with energies 10 3 MeV can be produced at distances up to 3–5 ( is the solar radius) within 700–1300 s.
